5. Operating Instructions
- Power On: After the device is fully charged, press the power switch (usually indicated by a power symbol) to activate the ultrasonic wave. The indicator light will illuminate, confirming operation.
- Frequency Adjustment: The device features adjustable sound waves. If the initial repellent effect is not satisfactory, locate the adjustment knob (typically on the top or side) and rotate it to change the ultrasonic frequency. Different frequencies may be more effective against specific pests (e.g., 20kHz for rats, 35kHz for squirrels, 50kHz for bats).
- Continuous Operation: For best results, allow the device to operate continuously. It provides day and night protection.
- Patience is Key: It may take some time for pests to be fully deterred. Consistent use over several days or weeks is recommended for optimal results.

7. Troubleshooting
- Device Not Turning On: Ensure the device is fully charged. Connect it to a USB power source and allow it to charge for several hours.
- No Apparent Effect on Pests:
- Verify the device is powered on and the indicator light is active.
- Adjust the ultrasonic frequency using the knob. Experiment with different settings to find the most effective range for the specific pest.
- Check for obstructions: Ensure furniture, walls, or dense foliage are not blocking the ultrasonic waves.
- Allow sufficient time: Ultrasonic repellents often require consistent use over several days or weeks to show full effectiveness as pests learn to avoid the area.
- Consider coverage: For larger areas, multiple devices may be necessary to ensure adequate coverage.
- Indicator Light Not Working: If the device is powered on but the indicator light is not working, the light itself may be faulty. The device may still be emitting ultrasonic waves. If the device is not functioning at all, refer to 'Device Not Turning On'.
